On Monday, Olympus lowered its full-year profit forecast by 5.7 percent because of the strong yen and weaker-than-expected digital camera sales, although it posted an operating profit of about $144 million for the three months to December.
Olympus is the world's third-biggest digital camera brand after Sony Corp (Tokyo:6758.T - News) and Canon Inc (Tokyo:7751.T - News).
Sony was down 0.94 percent at 4,200 yen and Canon fell 2.25 percent to 5,220 yen.
Smaller rival Casio Computer Co (Tokyo:6952.T - News) dropped 5.03 percent to 1,094 yen. Sanyo Electric Co (Tokyo:6764.T - News), which supplies digital cameras to Olympus under an original equipment manufacturer (OEM) deal, skidded 4.11 percent to 537 yen.
Fuji Photo Film Co (Tokyo:4901.T - News), which on Friday cut its full-year profit outlook partly due to a lower digital camera sales forecast, extended falls into a second session and lost 0.89 percent to 3,340 yen by mid-session. It lost 6.13 percent on Monday.
